CY7C1512  
64K x 8 Static RAM  
and three-state drivers. This device has an automatic pow-  
er-down feature that reduces power consumption by more  
than 75% when deselected.  
Features  
• High speed  
— t = 15 ns  
Writing to the device is accomplished by taking chip enable

• Low standby power  
Reading from the device is accomplished by taking chip en-

able one (CE ) and output enable (OE) LOW while forcing  
1
write enable (WE) and chip enable two (CE ) HIGH. Under  
these conditions, the contents of the memory location speci-  
fied by the address pins will appear on the I/O pins.  
• Automatic power-down when deselected  
• TTL-compatible inputs and outputs
